No password required . . . what?

Since not less than December and presumably a lot earlier, My Cellular Account has been displaying this data for each buyer account every time it’s offered with a legitimate Q Hyperlink Wi-fi cellphone quantity. That’s proper—no password or the rest required.

After I first noticed a Reddit thread discussing the app, I believed for positive there was some type of mistake.
